Abstract (en)
[origin: WO0135864A1] A multi-section filamentary stent comprises a braided section, which is a cylindrical mesh of a first set of filaments, connected to at least one wound section comprising a second set of one or more filaments having a repeating configuration with a bent portion. The two sections are preferably connected by at least one continuous filament extending into both sections. The two sections may be connected by a weld, a suture, a common graft, an overlapping portion of the two sections, or one or more filaments of one section looping through portions of the other section. The stent may comprise a first section, having a braided first stent architecture with a first flexibility and a first radial force, and a second section, having a non-braided second stent architecture with a second flexibility less than the first flexibility and a second radial force greater than the first radial force, in which at least one continuous filament is integral to both the first and second sections. The stent may also comprise one or more filaments in a repeating configuration having at least one bent portion, wherein the repeating configuration defines at least a first hoop comprising hexagonal cells, the first hoop axially adjacent to a second hoop that does not comprise hexagonal cells. The stent may also comprise a plurality of zig-zag or sinusoidal members wherein at least a first zig-zag member is overlaid upon a second zig-zag member and out of phase with the first zig-zag member to form an overlap between at least one strut of the first zig-zag member and one strut of the second zig-zag member. Methods for treating body lumen by implanting the stents as described herein are also disclosed, as is a method for counteracting a stent architecture end effect.
